MartinLogan Depth [6/24] Connections and control settings

CONNECTIONS AND CONTROL SETTINGS

MartinLogan engineers designed the Depth for easy setup

and system integration. Before beginning to connect your

Depth, please review the controls discussed in the last sec-

tion. An understanding of these will help speed you along as

you connect your Depth with your system. All signal con-

nections are done at the signal input section on the rear

connections panel of the Depth. Make certain that all of

your connections are tight.

WARNING! Turn your Depth subwoofer off

before making or breaking any signal connections!

2-Channel Mode

This setup is recommended if your Depth will be used in a

2-channel system with main speakers playing full range.

When a signal is connected to the Depth’s Left/Right Inputs,

the Depth’s internal low pass filter is active.

Signal Connection (see figure 2):

1 Connect the left and right outputs of your preamplifier to

the left and right inputs of the Depth using quality RCA

interconnects. If your preamplifier only has one set of out-

puts you may need to obtain Y adapters from your dealer.

Recommended Control Settings (see figure 3):

1 Set the 25Hz Level control to 0.

Set the low-pass filter switch to to the closest option equal

to 70% of your loudspeakers lowest frequency response.

3 While playing music with bass content, turn the level con-

trol up until the music has deep extended bass, being

careful to avoid levels that become overwhelming.

4 Try the phase control in different settings until the best

blending is obtained. If you are using the Depth to aug-

ment other MartinLogan products, we suggest you start

with the phase set at 90° (0° if you are using Script™

loudspeakers).

5 If you have completed steps 1–4 and still have weak or

boomy bass, adjust the 25Hz knob to compensate for

these anomalies. Turn the 25Hz control up and down and

listen to the effects that it has on the music. Try to find a

position that sounds correct to you. Experiment by chang-

ing the level control while adjusting this knob. You should

be able to find a position that gives you deep extended

bass and good blending with your main speakers.
